Log Message:
Pull up following revision(s) (requested by abs in ticket #1648):

        sys/arch/vax/vax/pmap.c: revision 1.196
        sys/arch/vax/include/trap.h: revision 1.25

Change CASMAGIC to 0xFEDABABE so that it cannot accidentally end up in
valid kernel memory.  Due to the VARM accesses above S0 should always
give a ptelen trap.

Bug found by Kalvis Duckmanton.

Ensure that the kernel do not try to allocate a S0 segment larger than 1G,
since the hardware prohibits that.
